Camden',;Gamd en county, New J ersey, have invented an I-mprovementin Lu'bricating'Wool;

, and I .do hereby'declare the following to be a full, clearyand exact description of the same.

My invention consists in the. use t'orlubricatin'g'wool preparatory to carding and spin- I ningithesameof the secretion extracted from the wool, so as to dispense with theusual costly lubricating materials.

consisting of soapy matter with an excess of 011. Before wool can be dyedand subjected to other. preparatorytreat'mehts--this secretion must be removed-an'operation usually accomplish'ed' bywashing' the wool in an alkaline lye, which, after taking up the soapy matter of the wool; has been hith'e to thrown away as useless. I-have discovered-that this matter can be used to'the best advantage in oiling the wool'preparatory to carding or spinning the Several modes of prepa in g the secretion for application totlic wool may beadopted'. The wool, for instance,.may be simply washed-in an alkaline lye, as usual, and the composition resulting from the union of the lye withthe' se-l cretion may be applied directly to the wool preparatory to carding or spinning the same, or-th'e secretion maybe removed fromthe wool by simply washing and rinsing the sam'ein warm water, with or without-the additionof a portion of common salt, the solution thus obstained to be applied directly to the wool-or laid aside for'futureuse. The secretion may be forced from the wool by firstlieating the lat; ter and thensubjecting it to pressure between rollers or other appliances, the matter thus obtained-beingof about 'the consistency of ordh i ary tallow, and admitting of being purified preparatory to its application tothe wool,-or the soapy matter thus obtained may lie-mixed with alkaline'lyc', or with olive-oil, lard-oil, or other material heretofore used for lubricating woo'l. After many practical tests I hate found that this. secretion appliedto the lubrication-V of wool serves the desired purpose mucli'better than lard-oil or any of thepreparationsof borax and water or other fluids. I have found, too, that the secretion extracted from the wool is available as a lubricant for machinery.

, The economy resulting from the practice of my invention-will become apparent when itis borne in mind that there isin wool nearly twice l as much of the fatty and soapy secretionas is necessary for the'oi-lingoi the wool prepara ,tory to carding or spinning, and that this val- HENRY Hows'oN, W.
